CAUTION:
Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
WARNING: MAKE SURE THAT THE TOTAL RMS CURRENT REQUIRED BY ALL APPLIANCES THAT ARE CONNECTED TO THE
SYSTEM’S PRIMARY AND SECONDARY POWER SOURCES, NOTIFICATION APPLICIANCE CIRCUITS, SM, DSM SYNC MODULES, OR
WHEELOCK POWER SUPPLIES DOES NOT EXCEED THE POWER SOURCES’ RATED CAPACITY OR THE CURRENT RATINGS OF ANY FUSES
ON THE CIRCUITS TO WHICH THESE APPLIANCES ARE WIRED. OVERLOADING POWER SOURCES OR EXCEEDING FUSE RATINGS
COULD RESULT IN LOSS OF POWER AND FAILURE TO ALERT OCCUPANTS DURING AN EMERGENCY, WHICH COULD RESULT IN
PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.
WIRING AND MOUNTING INFORMATION:
CAUTION:
The following figures show the maximum number of field wires (conductors) that can enter the backbox used with each mounting option. If these
limits are exceeded, there may be insufficient space in the backbox to accommodate the field wires and stresses from the wires could damage the product. Check that
the installed product will have sufficient clearance and wiring room prior to installing backboxes and conduit, especially if sheathed multiconductor cable or 3/4"
conduit fittings are used.
Although the limits shown for each mounting option comply with the National Electrical Code (NEC), Wheelock recommends use of the largest backbox option shown
and the use of approved stranded field wires, whenever possible, to provide additional wiring room for easy installation and minimum stress on the product from wiring.

•
This model has in-out wiring terminals that accept two #12
to #18 American Wire Gauge (AWG) wires at each screw
terminal. Strip leads 3/8 inches and connect to screw
terminals.
•
Break all in-out wire runs on supervised circuits to assure
integrity of circuit supervision as shown in Figure 2. The
polarity shown in the wiring diagrams is for operation of
the appliances.
* Refer to Sync Module instruction sheets SM (P83123), DSM (P83177) or Wheelock power supplies for additional information.
GROUNDING:
Connect ground wire to backbox. Install signaling appliance to backbox using mounting screws provided.
WARNING: CHECK ELECTRICAL RATINGS SPECIFIED IN TABLES 1 AND 2 (AS APPROPRIATE) TO ENSURE PROPER INPUT. BE SURE
THAT SPEAKER WIRING IS CONNECTED TO SPEAKER TERMINALS ONLY AND STROBE WIRING IS CONNECTED TO STROBE TERMINALS
ONLY. CHECK TO INSURE THAT WIRING AT FACP IS CORRECT. IMPROPER ELECTRICAL INPUT CAN DAMAGE THE PRODUCT OR
CAUSE IT TO MALFUNCTION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR
OTHERS.

1.
Each doubling of rated Watts increases sound output by 3
dBA. Field selectable input terminals are provided on
each unit. The following wattage selections are available:
1/8W, 1/4W, 1/2W, 1W and 2W.
2.
Each letter corresponds to a plug position of the header
located on the printed circuit board. Select voltage and
wattage as shown in Table 4 below.

A 1.5
µ
F blocking capacitor for DC supervision of audio
lines by the FACP is factory wired in series with the
speaker input.
NOTE: Use needle nose pliers to pull and properly insert the jumper plug to the desired tap setting.
